Abstract

The present invention provides a vibrating motor, which includes a casing, a vibrator and a stator housed in the casing, one of the vibrator and the stator includes a solenoid, and the other includes a magnetic circuit structure. The magnetic circuit structure includes: a first magnet part and a second magnet part respectively arranged oppositely at two sides of the solenoid; a third magnet part and a fourth magnet part respectively arranged oppositely at both ends of the solenoid. Compared with the related art, the vibration motor provided by the present invention has a magnetic circuit structure surrounded by four magnet parts, and the solenoid is arranged in the accommodation space surrounded by the four magnet parts, so that the magnetic force line is along the long axis direction of the solenoid. The two ends on the top are gathered, so that the driving force of the vibrator at the initial position is the smallest, and the driving force on both sides increases non-linearly. However, the driving force at the initial position is still more than twice the driving force generated by the traditional magnetic circuit structure, making the The response speed of the vibration motor is fast, the acceleration is large, and the frequency bandwidth is wide.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of motors, in particular to a vibration motor. [0003] 【Background technique】 [0004] With the development of electronic technology, portable consumer electronic products are becoming more and more popular, such as mobile phones, handheld game consoles, navigation devices or handheld multimedia entertainment equipment, etc. These electronic products generally use vibration motors for system feedback. Such as mobile phone call prompts, information prompts, navigation prompts, vibration feedback of game consoles, etc. Such a wide range of applications requires high performance and long service life of the vibration motor. [0005] The vibrating motor in the related art includes a casing, a vibrator arranged in the casing, and a stator matched with the vibrator. The vibrator includes a counterweight and a magnetic steel embedded in the counterweight. The stator includes a fixed Due to the coil of th...
